SELF-ANCHORING STUMP PULLING AND HOI STING- APPARATUS.

A pp lieation file'd April 23, 1909. Seria11io.491,696.

To all whom 'izfmay Be it known-that we, ALEXANDER M.

SEMRAN and ,KENNETH- SQFORB'ES, citizens of the'United' States, residing at Odessa, in

' the county'of Bigstone and State of Minne:

sota, "ha've invented new and useful Im- "prov'ements in Self-Anchoring Stump Pulling andHoi sting Apparatus, of wh ch the following is a specification.

- This invention relates to. self-anchoring stum pulling and hoisting apparatus, and

has or an object to provide a novel form apparatus can be effectively held in the deof anchor adaptedtobe' actuated when the apparatus is moved forward and to be em bedded in the ground to the extent that the sired position, and to further provide effective means for adjusting the anchors when they have been withdrawn from the ground and to raise the said anchor so that it will be entirely out of the way when the machine is propelled.

Other objects and advantages will be apparent as the nature of the invention is better set forth, and itwill be understood that changes within the scope of the claims may be resorted to without departing from the spirit of .the invention.

In the drawings, forming a portion of this specification and in which like'numen' als of reference indicate similar parts in the several views:'Figure 1 is a side elevation of our improved stump pulling and hoisting apparatus. Fig. 2 is a top plan view. Fig. 3 is a detail front elevation with parts in section and with parts removed to more clearly illustrate the construction and arrangement of various parts. Fig. 4 is a diagrammatic view of the anchor showing the adjusting means therefor.

In the drawings, there is shown a stump puller andhoisting apparatus embodying a frame comprising longitudinally extending side bars 1 and 2 and connecting cross bars 3. The frame is also provided with a longitudinally extendingv bar 4 disposed in juxtaposition to the bar 1 and in suitable spaced relation therefrom as clearly illustrated in Fig. 2 of the drawings. The frame is provided at the rear end thereof with a platform 5 upon which the operator of the apparatus can stand when the apparatus is in use. The said frame is provided with front and rear bolsters 6 and 7, the former provided wit-h a. wheeled axle 8, the wheels thereon being disposed directly beneath the Specification of Letters Patent Patented May 21, 1912.

longitudinal bars 1 and 2.- The bolster 7 is similar in construction to the bolster 6 and carries a wheeled axle 9, the wheels of which extend outwardly beyond the sides of the frame as shown in Fig. 2 of the drawings to more efi'ectively steady ,themachine or apparatus as is obvious.

An anchor 104 is provided for the apparatus'and it-vembodies members 105 and 106 pivoted at their-upper ends beneath the bars 1 and 2 of the frame and are thus free to swing angularly as will be understood. The

members 105 and 106 are provided with cables 107 and 108 engaged with a screw or worm 109 carried byv the frame of the apparatus and provided with a crank handle 110 so that the screw or worm 109 can be revolved to adjust the anchor members 105 and 106. In order that the said members can be held in' their adjusted positions we connect with the same chains '111 t'helinks of which being adapted to securesupporting hooks 112 upon the longitudinal'side bars of the frame, The anchor membersv 105 and 106 have pivotally connected thereto a transversely disposed anchor plate 113 disposed rearwardly of the pointed ends 114 of the members 105 and 106. I

' It will be seen that when it is desired to extract a stump, the machine or apparatus described may be propelled in any suitable manner so that it can be properly positioned with respect to the stump to be'extracted, and by first adjusting the links of the chains 111 with the hooks 112 the forward pointed ends 114 of the members 105 and 106 can be effectively embedded in the ground tothe extent that the entire apparatus will be held stationary and in its proper position relat-ive to the stump to be extracted, and the machine will be prevented from movementtoward the stump during the pulling operation. To provide. more effective means for holdin the machine against movement when it has been moved into its operative position we provide at the ends of the transverse member 48 brackets 115 to which are pivotally connected the upper ends of meml'rs or legs 116 rovided with spuds or ground engaging e ements 117. The members or legs 116 are provided with sliding collars 118 to which the lower ends of brace arms 119 are connected, the upper ends of said'brace arms being connected pivotally to the longitudinal bars of the frame.

Vthen it is desired to move the members or tending legs 116 out of engagement with the ground they are swung upwardly as will be understood and may be heldin their adjusted positions by providing the bands 118 with re: movable pins or the like120 to be engaged in apertures 121 formed in said members or i s a brace for the crane hereinbefore de scribed we provide the frame of the apparatus with a beam or member 122 havinga cap member 123 provided with a forwardly explate 124 which receives a vertically extending pivot pin 125 at the upper end of the mast 51. 1

To limit .the forward movement of the legs or members 116 we connect therewith chains or similar connections -140 adapted to be adjustably connected to hooks 141' upon the longitudinal side members of the frame.

We 0 aim I 1-. In a stump puller, a portable frame, a

pivotally mounted main anchor beneath the frame, operating mechanism for moving the anchor to' an elevated position, means for holding the anchor againstfpivotal movement in onedirection, spuds pivotall supported b the frame and located inv a vance of the e ective anchoring end of the main anchor, and a supplemental anchoring member pivotally supported bysaid main .an-- chor and embodymg a relatively wide plate extending transversely beneath the frame and disposed above-the plane of the efi'ective anc oring end of the main anchor.

2. In a'stump puller, a portable frame, a

ivotally mounted main anchor pivotedadacent to the rear of the frame, and extending downwardly in the direction of the front of the frame, operating mechanism for moving .the. anchor to an elevated position, means for holding the anchor against pivotal movement in one direction, spuds pivotally supported by the frame and located in advance ofthe effective anchoring end of .the main anchor, and a supplemental anchoring member pivotally supported by said main anchor and embodying a relatively wide plate extending transversely beneath the frame and disposed above the plane of the effective anchoring end of the main anchor.

3. In a stumppuller, a portable frame in- I eluding longitudinal side bars, companion main anchors pivoted at their rear ends beneath the side bars of the frame and extending downwardly in the direction of the 7 front ofthe frame, operating mechanism for simultaneously moving the companion anchoring members to inoperative positions, a supplemental anchor connecting the companion main anchors with each other and pivotally mounted on the main anchors and points in advance of the main y supported upon the frame and lo.-.
